Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a flat surface and engage the parking brake.
  • Disconnect the battery to avoid electrical issues.
2. Remove Wheel
  • Use a jack to lift the vehicle and secure it on jack stands.
  • Remove the wheel using a socket set and torque wrench.
3. Inspect and Replace Brake Components
  • Inspect Brake Pads:

    • Remove the caliper bolts using a socket wrench.
    • Slide the caliper off the rotor and inspect the brake pads for wear.
    • If worn below specification, replace with new pads.
  • Inspect Brake Rotors:

    • Check the rotor surface for warping or scoring.
    • If warped beyond tolerance, replace rotors.
    • Clean the mating surface of the hub and rotor.
4. Reassemble Components
  • Reinstall the caliper over the new brake pads or rotors.
  • Tighten caliper bolts to manufacturer specifications (usually around 30-40 Nm).
  • Reattach the wheel and torque the lug nuts to the specified value (typically 120 Nm).
5. Test Drive
  • Lower the vehicle and remove jack stands.
  • Reconnect the battery.
  • Test drive the vehicle to ensure the vibrations during braking have been resolved.
